I think the FL (Cecil) and ML (Estian) child is Girgantia the dragon in the past?? maybe they child became a monster just like Estian thought that his will became a monster because of his blood, that is why he don't want to have a child. Thief child became a (⌒▽⌒)Dragon because of the Estian Eugendiph's blood. besides, The Drangon Lord told to Cecel that Girgantia was her son not hers.
